How can we fetch element from the ArrayList?
a. retrieve()
b. get()
c. containsValue()
d. find()
Solution
We can fetch an element from the ArrayList using the get() method. Here is a step by step guide:
- First, you need to create an ArrayList. You can do this using the following code:
ArrayList<String> list = new ArrayList<String>();
- Next, you can add elements to the ArrayList using the add() method. Here is how you can do it:
list.add("Element1");
list.add("Element2");
list.add("Element3");
- Now, if you want to fetch an element from the ArrayList, you can use the get() method. The get() method requires the index of the element that you want to fetch. Here is how you can fetch an element:
String element = list.get(0);
In this case, the get() method will return the first element of the ArrayList. Remember that the index of the ArrayList starts from 0.
So, the correct answer is b.get().
